I worked briefly on projects within the Business Intelligence system. The system is well set up, with a lot of attention paid to technical coherence and system stability. It's very clear what the constraints are within which development takes place in this system. I was a contractor, but some permanent colleagues were working on innovative projects including integrating of map data.

Cons

The flipside of the level of attention paid to system stability and release process is invevitably that the processes could sometimes feel a bit burdensome. This is still preferable to an uncontrolled environment with constant firefighting and chaos. There were some problems involving team members located in far-distant timezones, which sometimes made communication difficult. The hours of work (8-4) are not my favourites hours of the day!
